Title: Method for improving the activation of latently hydraulic basic blast-furnace slag in the production of a building material
Inventor: KURZ FREDRIK W A
IPC: C04B7/153
Filed: 1991-10-01
Abstract: The invention relates to a method of improving the activation of latently hydraulic granulated basic blast-furnace slag in the manufacture of building materials. Known activating methods can be improved by a combination of activating agents, whereby the latently hydraulic slag is converted to a directly-acting hydraulic binder, which together with water and aggregate, such as sand and gravel, will produce a concrete of high tensile and high compression strength, and also a concrete which has good chemical resistance to attack by salt, sulphates and chlorides, and which is heat-resistant to temperatures up to 1000 ·C. Activation is also able to eliminate the negative effect of aging. The improved activation is achieved by adding to the concrete mix a limited amount of alkali, a limited amount of Portland cement and optionally calcium oxide and amorphous silica powder, and an activator which includes magnesium oxide and phosphate.

Abstract: ABSTRACT: KIPPIES CLOTH  DIAPER       Kippies Diaper's are a cloth diaper that are made for a Human Baby. They are made from 100% cotton. Inside they have 8 layer's of cotton sewen directly to inside of diaper so there is no movement of inner layer's. This is for urine absorbentcy. They also have P.V.C. coated nylon (420 Denier) inside which  is equivalent in size of diaper. No plastic pant's are needed. The outside of the diaper is a printed cotton of clown's,balloon's,car's flower's,ect... All diferent types of print's for uniqueness.  This makes the diaper nice enough to be worn by itself as pant's.It comes with a 3 layered cotton liner that is fastened in with Velcro on inside, top,back of diaper, for easy removal for cleaning soiled diaper's.Also the velcro aides in holding up in back of diaper so it doesn't wrinkle dow? into groin area of diaper. The diaper also Velcro's closed in front,so no pin's are needed.All velcro on diaper is "VELCRO"Trade Mark Brand.Hook side is# 80 and Loop side is # 3610 .This is unique in the quality of the diaper because the rules that ap?ly with these two types of velcro give this diaper top quality in fastening strength. So diaper dosn't pop open when baby bend?s at waist. The range of fit for these diaper's are new-born to at least 26 lb's, or potty trained.Making it long lasting in size. the diaper also has elastic in leg's gathering material so to give a snug fit in groin area and help's prevent leakage.This diaper also has a steatchy waist band alon? the back to help close up along baby's back,stoping draft's and also stool leakage.                 Also on front Tab's of diaper there is a hook peice of velcro which is used to fasten diaper closed. There is also along side that peice a loop peice of velcro so hook part can be fastened back against it enabling the diaper to be placed on and taken off of baby without velcro part scraping baby.         Also velcro in liner's can be perchased  aditionaly in seperate packages in the event that they become soiled they can be replaced,.   signed Brenda Tardiff

Title: Optical signal identification technique
Inventor: FISHMAN DANIEL A
IPC: H04B10/142
Filed: 1993-08-16
Abstract: OPTICAL SIGNAL IDENTIFICATION TECHNIQUE            Abstract A wavelength-multiplexed optical signal identification technique in which each of the individual optical signals within a multiplexed signal are modulated at a unique low-frequency. This modulation is performed at the transmission site of the optical signal, and the specific frequencies of modulation are chosen to be very much lower than the low-frequency cut-off of any other information encoded upon the optical signals. At the reception site of the multiplexed signal, the invention directs each of the individual optical signals, as a function of the particular low-frequency modulation evident upon each signal, to a particular tunable Fabry-Perot optical filter. As Fabry-Perot filters have the ability to track the frequency of an individual channel, problems associated with wavelength drift are eliminated. Furthermore, Fabry-Perot filters offer a very narrow optical passband, allowing inter-channel cross-talk and noise levels to be minimized within wavelength-multiplexed optical systems employing the signal identification technique.

Title: Single step sterilization wrap system
Inventor: BOURNE SONYA N
IPC: A61B19/08
Filed: 1993-12-09
Abstract: Disclosed herein is a single step sterilization wrapping material suitable for use, as an example, in wrapping surgical instruments and supplies for sterilization, transportation and storage. The material includes separate inner and outer wraps which, unlike previous wraps, are joined to one another. Common wrapping techniques involve wrapping items to be sterilized with two separate sheets of wrap. The present invention provides separate wraps which can be specially engineered to deliver specific properties for each sheet and then joined to one another so as to permit wrapping and opening in a neat single step process which increases efficiency and saves time and money. In special situations the outer wrap can be engineered with increased strength, the inner wrap with increased barrier properties and the inner and outer wraps can be made visually distinct from one another so that improper wrapping or opening is not a problem.

Abstract: A precast concrete floor slab for a structural floor system has a flat floor panel of polygonal form, with a peripheral perimeter beam around the outside of the floor panel and intermediate beams radiating from the centre of the floor panel to the perimeter beam. In use, the slab is supported at its corners on piles, with adjacent slabs being arranged side by side to cover the necessary floor area. No grade beams are required as the perimeter beam of each slab provides the necessary structural strength for supporting the building. The intermediate beams under the slab allow the thinning of the slab to reduce the overall amount of concrete used. The slabs are fastened in place with loops of the slab reinforcement that project from the slab at the corners for connection to the reinforcement of the piles supporting the slabs.

Title: Use of selected inhibitors against the formation of solid organic-based incrustations from fluid hydrocarbon mixtures
Inventor: VON TAPAVICZA STEPHAN
IPC: C10L10/04
Filed: 1992-12-22
Abstract: A method is provided herein for inhibiting the formation of solid hydrocarbon incrustations from hydrocarbon mixtures which are fluid and prone to form such incrustations. The method includes the step of contacting the hydrocarbon mixtures with an inhibitor mixture comprising esters of phosphoric acid or salts thereof and alkoxylated aliphatic alcohols, alkoxylated cycloaliphatic alcohols or alkoxylated aromatic alcohols, and fatty acid oligo-dialkanolamides. These inhibitor mixtures preferably have a surface-active character and are capable of wetting, and especially of spreading on, solid work material surfaces in the presence of the fluid hydrocarbon. These inhibitors are especially useful for the protection of pipelines, pumps, filters, tanks and metal surfaces against the formation of incrustations thereon.
